The movie opens on the night Nora Allen was murdered. We see black, red, and yellow lightning surrounding both Nora Allen and child Barry Allen. Suddenly the yellow and black bolts disappear and only the red lightning remains. The man goes in to kill the child but Nora jumps in the way. Just then the yellow lightning returns and pushes the man into a portal. The man and the yellow lightning land at the end of time and out of the yellow lightning steps Barry Allen who calls the man Reverse. Reverse tells Barry that his mom must die that night or else the timeline will break. Reverse tells Barry at first it was about ruining Barry's life but now they are in a loop and on that night she must stay dead. Barry runs back to that night where he stops the Reverse and saves his mom. We cut back to the Reverse who gets powered up by the Speed Force with black lightning and while running to stop Barry drops some lightning on both Henry Teller and Zolomon Hunter. Once Reverse gets there Barry is fighting the Reverse and so Black Reverse goes in with the black lightning just as the Barry Allen that was supposed to visit that night shows up. Reverse pulls Barry out of there and attacks him. Reverse takes off his mask and reveals himself to be Donald Drake aka Eobard Thawne. Barry gives up and asks Eobard to help him. The two head back in time to the beginning of that night and Barry stops himself while Eobard makes sure past Eobard kills Nora. The screen goes black and the credits roll.
